Air Temperature Reductions at the Base of Tree Canopies
Journal of Sustainable Water in the Built Environment, 2021Trees in urban settings have a significant role in regulating urban hydrologic cycles. Urban trees, either as standalone plantings or as part of a tree pit, are an increasingly popular stormwater management tool. Beyond their aesthetic contribution to urban environments, trees are widely accepted as reducing the ambient air temperature.

Variations in canopy temperature, relative humidity and soil temperature within crop micro-environment exert full control over plant’s physiological processes and thereby over growth, development and yield of crop. These micro-meteorological parameters tend to significantly control the exchange of energy between the crop environment and the atmosphere.

Land surface temperature (LST) is an important parameter that modulates land surface process. The combination of infrared temperature and microwave temperature is a trend in the research of LST. Thermal infrared temperature and microwave temperature have different physical significances and values.

Canopy Temperature Response to Water Stress under Partial Canopy
Transactions of the ASAE, 1985ABSTRACT UNSTRESSED baselines of the crop water stress index for cotton under full ground cover have slopes about twice those under partial canopy cover. These results were consistent between four strains and one commerical variety and were caused by a more aerodynamically rough canopy under partial ground cover.

Radiative balance and temperature of differently pigmented cotton canopies
International Journal of Biometeorology, 2022Pigments are known to modify the spectral properties of foliage, which in turn affect the amount of radiant energy stored by the plant canopy. Studies have shown that red pigments (anthocyanin) increase leaf absorptivity of solar radiation, but little is known about their effect on canopy net radiation and temperature.

Azimuthal radiometric temperature measurements of wheat canopies
Applied Optics, 1981The effects of azimuthal view angle on the radiometric temperature of wheat canopies at various stages of development are investigated. Measurements of plant height, total leaf area index, green leaf area index and Feeks growth stage together with infrared radiometric temperature measurements at 12 azimuth intervals with respect to solar azimuth and at

Air-canopy temperature difference for fluorescence emission models
IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004Precise canopy temperature (CT) determination of a boreal forest region was needed within SIFLEX-2002 to improve the understanding of fluorescence processes. Taking into account sky radiance effects and emissivity correction, CT was measured with an accuracy of /spl plusmn/0.4 K using the CE 312 radiometer.

A hand‐held infrared thermometer was used to measure the leaf canopy temperature of 20 soybean [Glycine max (L.) Merr.] genotypes under both irrigated and nonirrigated conditions. In 1980, 14 canopy temperature measurements were made end 9 were made in 1981.

Soil and vegetation canopy temperature gradients: implications for SMOS
IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004We present the diurnal variation of vertical temperature gradients measured in a maize canopy over the course of a growing season in the context of the SMOS mission. For the 6 AM and 6 PM overpass times, gradients were actually smallest in magnitude at 6 PM. The mean, standard deviation, and extreme values of the temperature differences between the top
